DETAILED DESCRIPTION OF THE INVENTION

Detailed description of present invention is as following:

FIGS. 1-3 reveal a plate type image display device, which comprises:

A light impermeable plate (1); and

A display device (2) which is disposed in one side of and have adistance with said plate (1), said display device (2) is also capable ofprojecting light on the surface of said plate (1);

Said plate (1) comprises plurality of tiny cylinder holes (11) which arethrough both surfaces of said plate (1), every single of said cylinderholes (11) is filled with a crystal transparent pillar (12), one end ofsaid pillar (12) is a light incident end (12 a), which receives thelight from said display device (2), then guide the light to another end(12 b) of said pillar (12), furthermore, the surface on the inner wallof said holes (11) is a light reflective surface (13).

Said display device (2) is a projector (21), the plate (1) looks justlike a normal wall, the display device could not be seen from the otherside of the plate (1) before the display device (2) is activated, oncethe display device (2) is activated and the light is projected on thesurface of said plate, the light would be guided to the other side ofthe plate (1) through said pillar (12), and form plurality light spotson the other side of the plate (1), and the image displayed on the plate(1) is composed of said light spots, thus, present invention is morelike a hidden display screen, when said plate (1) is installed on theoutside of the building or wall, the plate (1) could become the surfacelayer of the building or wall, once the display device (2) startsprojecting, said plate (1) soon becomes a commercial display board, thedisplay effect of present invention would be better when using in thenight.

Said pillar (12) is crystal transparent and highly light permeable, alsoseals the tiny holes (11) on the plate (1), thus, the wind or rain wouldnot go through the plate (1) from said holes (11), and affect the othersurface of said plate (1). Also, said pillar (12) is made of highlylight permeable plastic material such as Polyethylene, Polypropylene,and Polyvinyl Chloride ect, the production method of making said pillar(12) is to heat and melt said plastic material into liquid, and injector press the liquid into said holes (11), the pillar (12) would beformed when the liquid plastic material cooled down and become solid,the making method is simple and cheap, and also could be producedrapidly and massively, thus, the price of said plate (1) is dramaticallyreduced.

The material of said pillar (12) could also use highly light permeablecrystal transparent glass, with better light permeability and lightguiding effect, but, whether use plastic or glass to make said pillar(12), both have awesome water and vapour proof capability.

As shown in FIG. 4, the surface on the inner wall of said holes (11) isa light reflective surface (13), thus, while the light projected fromthe display device (2) entering the pillar (12), would be reflected bysaid light reflective surface (13) and guided to another end of theplate (1) to display brighter light spot, so the color reproduction ofpresent invention is increased, furthermore, over 20000 holes aredeployed on single unit area (ex: Length 1.5 m, width 2.5 m) of saidplate (1), thus, plurality of light spots appear when said displaydevice (2) is projecting light.

Said plate (1) is durable and widely applicable, thus, present inventionis capable of both using indoor and outdoor, when present invention isused outdoor, the quality of displayed image on present invention isstable and clear, and being less affected by outrage weather, andDefective pixel problem would not be occurred. Furthermore, the powerconsumption of present invention is only 6˜10% of conventional LEDdisplay, and complex maintenance procedure is not required for presentinvention, therefore, the deploying and maintenance cost of presentinvention is much lower than prior art.

As shown in FIG. 5, present invention is composed of one display device(2) and one plate (1), however, multiple plates (1) and display devices(2) could be applied for the demand of large scale screen.

As shown in FIGS. 6 and 7, present invention could also be applied onthe building (200) or vehicle (300), and the size of said plate (1) isadjustable for user's need, when the display screen is assembled bymultiple plates (1), there would be seamless in the connecting part,also match the original display ratio of the image projected from thedisplay device (2), the brightness and display area of the plate (1)could also correspond to the size and brightness of the image projectedby the display device (2) without affecting the appearance of thebuilding (200) or vehicle (300), furthermore, the appearance of theplate (1) installed on the surface of the building (200) or vehicle(300) could involve in its appearance, and become a part of structure ofthe building (200) or vehicle (300) instilled on.

The diameter of each said cylinder hole (11) is 0.1 to 5 mm, which isselectable for corresponding the size of the original image from thedisplay device (2).

The minima thickness of the plate (1) is 1 mm, or, the quality of theimage shown may be affected, however, with the increase of the thicknessof said plate (1), the weight of the plate (1) would also upgrade, whichis another disadvantage for mounting and moving, thus, to choose properthickness of said plate (1) by practical demand is required.

Secondly, said plate (1) is made of metal or plastic, the polishingprocess could be applied if the plate (1) is made of metal, to upgradethe reflecting rate of the reflective surface (13), thus, a reflectivewall is formed to guide the incident light from one to another side ofthe pillar (12), this method is convenient, fast, cost-low, and shortenthe time of production effectively, furthermore, once the pillars (12)are injected, which are tightly attached on the wall of the cylinderholes (11), said reflective surface (13) achieve better protection whichmakes said reflective surface (13) become more durable from weatheringand detaching.

Furthermore, the outside of said reflective surface (13) could be platedwith a metal film (14), said metal film (14) could be formed byelectroplating, dip plating, spray-coat plating or chemical plating,which are common skill of the field.

As FIG. 9 shown, the display device (2) is display screen (22), FIG. 9reveals a large plate (1) combines with multiple display screens (22),the image of said display screens (22) is integrated by video splitter.The type is appropriate in the situation which needs to display largescale images, as description above, present invention is adaptive andconvenient in different conditions and places.
